Dr. Byrne had discussed my visit with my PCP earlier 2/2 blood pressure issue and they agreed to start me on a BP Rx. She suggested I get a new BP monitor since mine is a few years old and may not be as accurate any more. Also wanted me to note am and pm BP while on the new medication for tge next few weeks.
